I am designing a PCB for Kinetis K22 and have some confusion in SWD connector pin configuration.
There are two different configurations available, one is SWD connector in FRDM-K22F schematic (TDI and TDO pins are not used).
The other configuration is available in user manual of PE Micro U-Multilink (TDI and TDO pins are used).
I would like to know about the difference in these two configurations (how is it possible to program microcontroller without TDI and TDO pins)?
I intend to use PE Micro U-Multilink programmer for programming my custom board MCU, which of the two pin configuration should I use?
